Hyundai sante fe project. Running and driving.

2011 Hyundai Sante Fe. No offers. Running and driving. Selling complete car only. 127k miles. Had 4 new tyres on and then the ECU went mental. It was going into limp and the error message was giving a problem with the accelerator pedal position. This was all replaced but same issue. Mechanic had the car for months but has advised he’s not able to sort it. Could be a problem just with the ECU. We have already bought a new car so this is going. It does have dings and scraps but no rot. Will need trailered as although it runs, it’s unpredictable power wise because of the ECU and out of MOT. No offers
